1931- -J. CICOUREL KEY HEAD COVER 7 Filed Oct. 18, 1930 INVENTOR 1.; Jame 97a 6 Patented Dec. 15, 1931 UNITED STATES JOSEPH CIOOUBEL OF NEW YORK, N. Y.

KEY HEAD OOVEB Application filed October 18, 1980. Serial No. 489,688.

This invention relates to key attachments and more particularly toa key head cover, the invention having as its object to provide a cover of resilient sheet metal which may be fitted to the approximately circular head of any ordinary key, and the invention constitutes also an improvement on the key cover disclosed in my copendin-g application filed April 26, 1930, Ser. No. 447,688.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings, and specifically pointed out in the appended claims, it being understood of course that mmor changes may be made so long as .they fall within the scope of the claims.

In describing my invention in detail, reference will be had to the accompanying drawings, wherein like characters denote like or corresponding parts throughout the several views, and in which:

Figure 1 is a view in side elevation of one embodiment of the invention applied to a ke Figure 2 is a sectional view on the line 2-2 of Figure 1, looking in the direction indicated by the arrows.

Figure 3 is a view similar to Figure 1, illustrating a modification of the invention.

Figure 4 is a sectional view on the line il; of Figure 3, looking in the direction indicated by the arrows.

Figure 5 is a plan view of the blank from which the embodiment shown in Figures 3 and 4 is formed.

Figure 6 is a view similar to Figures 1 and 3 showing another embodiment of the invention.

Figure 7 is a sectional view on the line 7 7 of Figure 6, looking in the direction indicated by the arrows.

Figure 8 is a plan view of the blank from which the cover shown in Figures 6 and 7 is formed.

In the embodiment of the invention illustrated in Figures 1 and 2, the cover comprises two side members indicated by the 7 numeral 1 and which members are initially cal form and a connecting margina of such contour that when they are pressed or stamped, each will comprise two portions 2 which are of approximatel elliptil portion 3 whlch constitutes the fold between the two pairs of portions 2. There is of course a dividing space between the adjacent margins of each two of the portions 2, and this space is increased inwidth near the upper side of the cover as indicated by the numeral 4 so as to expose the usual openin 5 which is formed in the key head 6. ThlS embodiment, being made of resilient sheet, it is a simple matter to apply the same to and remove the same from a key head by merely springing apart the two sides thereof, the connecting portion 3 being at such time, flexed.

In the embodiment shown in Fi res 3, 4 and 5 of the drawings, the cover 15 formedfrom a blank of the marginal contour shown in Figure 5 and comprises two substantially circular side portions which portions are connected by a narrow shank portion 8 formed with a slot 9 extending longitudinally thereof so that the blank, at the time it -is fitted to a key, may have the shank of the key inserted through the slot.

Openings 10 are formed in the members 7 and these openings are brought to posi tion opposite each other and into registration with the opening 5 in the ,key head 6 for the purpose set forth in connection with the first described embodiment of the invention. Preferably, in applying a blank, shown in Figure 5, to akey head, the portion 8 is" longitudinally flexed or curved so as to conform to the curved margin of the key head, and in order that the device may be securely held in place upon the key head, one of the portions 7 is formed with a relatively short tongue 11 extending from-one side of the margin of said portion, and with longer tongue portions 12 which extend one from the other side of the portion 7 at the margin thereof, and the other tongue 12 extends from the margin of the portion 7 at a point opposite the opening 10. The other portion 7 is provided with tongues13 arranged similar to the tongues 12 of the first mentioned portion 7 with a single tongue 14 longer than the tongues 13 and arranged similar to the tongue 11, but at the posite side of the respective member 7. t will be observed 6 by reference to Figures 3 and 4 that these tongues are all folded down against the margin of .the key head and, the longer tongues are folded to extend over the margin of the key head and in overlapped relation to the respective shorter tongues and also into overlapping engagement with the rtions 7 other than the portions upon whic they are formed.

The embodiment of the invention shown in Figures 6, 7 and 8 is also formed from resilient sheet metal and preferably from a blank such as shown in Figure 8 of the draw ings, and this embodiment comprises two side portions 15 which are approximately circular '2 and connected by a relatively narrow web portion 16, each portion 16 having an openmg 17 therein, and these openings correspond to the openings 10 of the second described embodiment. Arcuate flanges 18 are formed at the side margins of each of the side members 15 and these flanges overlap when the blank is folded at its web portion 16 as clear-- ly shown in Figure 7 It will be evident from the foregoing description of the inven-' 80 tion that any of the'forms of cover herein shown and described may be readily adapted to the circular head of any ordinary key.

What I claim is: 1. A key head cover com rising a resilient 85 sheet metal body having si e ortions to engage the o poslte sides of a ey head, and marginal anges extending inwardly from the opposed faces of the said side portions to engage the margin of the head, the flanfis .40 having relatively spaced ends to receive tween them the shank of the key.

2. A key head cover com rising a resilient sheet metal body having si e ortions to engage the ?poslte sides of a ey head, and

marginal anges extending inwardly from the opposed faces of the said side portions to engage the margin of the head.

In testimony whereof I aflix my signature.
